Never liked eating cereal at breakfast anyway. I crash after a half hour, feel hungry again, and generally hate the rest of the day. Cereal is not a breakfast food, it's an after-dinner snack.
Admittedly part of that problem is that a lot of high calorie (though not necessarily healthy) food is available very cheaply, and a lot of things people do for entertainment these days do not require anything beyond sitting on a couch.
